  1. Hello, I'm trying to compress fraps video following this tutorial:
    https://www.youtube.com/watch?v=-Gobx4hcW8E
    except that I used after effects instead of sony vegas

    now problem is that if I play the resulting video of lagarith or the final mkv video with WMP, VLC or MPC then colors are washed out! But with GOM Player and Youtube it looks OK!
    how to fix this so it would play correctly on all players?
    thanks.

    with most players

  2. too complex to describe with such low amount of details but check for: quantization range YCbCr(16,235;16,240) vs YCbCr(1,254;1,254) vs YCbCr(0,255;0,255) vs RGB(0,255) issues.

  3. I've edited the post with more details, hope it's easier to explain now

  4. place snapshots for each configuration screen - in this YT link i see lot of problems - always remember that rendering in HQ for YT have no sense as YT will recompress video anyway thus you can safely render veryfast preset or even fixed quantizer, same for audio - see no point to struggle with settings HQ when YT will recompress this anyway with own settings.
    There is a chance that there is some issue on quantization range and/or color space (601 vs 709) - i see that in video this area is untouched when x264 is setup.

    Not sure about you target (i.e. if the video you doing is for YT only or also for other use) but probably it will be better to provide all information in final h.264 file anyway.

    Similar problem mentioned https://forum.videohelp.com/threads/321024-YouTube-HowTo-Lossless-unchanged-color

    Also i need to wait for doom9 begin operate back as http://forum.doom9.org/showthread.php?p=1556914#post1556914 i need to check if full range for Fraps is 1,254 or 0,255 .

    Anyway not sure how your video editor works (Adobe After Effects) - if it limit (saturate) YUV to 16,235 or pass 0,255 - perhaps this is main problem.

    note if I upload the video on YT it looks fine but if I downloaded it and played it with MPC and others it looks washed out again, and that's the heart of the problem, I want my videos to play correctly online and offline.

  6. Fix your MPC or graphics card settings.

  7. how it's a graphic card issue if GOM player plays the vid just fine?
    Quote Quote  
  8. RGB (what you see on the screen) vs. YUV (what's inside most video files) and how the transform is handled in software or by the graphics card.

  9. Last screen V.U.I. try to set quantization Range as Full http://mewiki.project357.com/wiki/X264_Settings#range , color primaries and color matrix as bt709. currently there is no information on this and various players "guessing", beware also of the fact that VUI can be ignored by h.264 decoders (player) and still you can have issue http://mewiki.project357.com/wiki/X264_Settings#Video_Usability_Info . But defining this will give at least some chance to avoid this problem.

    Sounds like everything's working correctly. YouTube expects levels between 16-235 and expands them to 0-255 in the player. That's why your images look flat on the PC and correct on YouTube playback.

    Want them to look different in your player? Adjust your player or make another version of your video for PC-only viewing with levels between 0-255. If you uploaded THAT one to YouTube, you'd notice the darks were too dark and brights blown out.

    unfortunately this didn't solve the issue, quantization Range has three values: auto, pc, tv
    pc gives the same old result
    tv makes colors a lot darker

    I see, but what's so special about gom player so it's able to play the pc and YT version correctly without any further settings tweeking?

  12. Check the settings between the players, especially the renderer used. That is likely the difference

    It's obviously not an encoding issue. It's a playback configuration issue . You cannot control how people have their playback software configured

    BTW - the description isn't "washed out", it actually should be "more contrast" . Washed out implies less contrast, elevated black levels

    Be sure to check only one player at a time , then close it before you check another.

    yeah, you are right, I've changed the renderer of MPC to madVR and colors look fine now, it's more like a dead end though!

    thank you everyone for you time.

    They would all look fine (as far as colors/contrast are concerned) if your graphics card was set up properly.

  15. Different renderers use different hardware functionality - driver settings usually exposed this as separate color profiles for different screen types. In typical graphic card there can be different video data paths - some of them are special video some normal graphic data, some can use 3d path.

    Anyway setting VUI is highly advised even if some retarded software ignoring VUI.
